PACKBME

The PACKBME is designed as a dual-channel keyboard or mouse port termination device. It integrates EMI/RFI filter components R1 and C1, and also incorporates two pull-up resistors R2. In addition, it provides a very high level of protection for sensitive electronic components that may be subjected to electrostatic discharge (ESD).

PACKBME has three features. (1)One keyboard or mouse port terminator, EMI filter and transient overvoltage protector in a single surface-mount package. (2)Compact SOT23-6 package saves board space and lowers manufacturing costs when compared to discrete solutions. (3)Excellent ESD protection: in-system protection to +/-30kV contact discharge per IEC 61000-4-2 international standard. Those are all the main features.

Some absolute maximum ratings have been concluded into several points as follow. (1)Its storage temperature range would be from -65°C to 150°C. (2)Its supply voltage (Vdd-GND) would be 5.5V. (3)Its DC power per resistor would be 100mW. (4)Its DC power package rating would be 225mW. It should be noted that stresses above those listed in absolute maximum ratings may cause permanent damage to device.

Also some electrical characteristics of PACKBME are concluded as follow. (1)Its R1 resistance would be min 31ohms and typ 39ohms and max 47ohms. (2)Its R2 resistance would be min 3.7kohms and typ 4.7kohms and max 5.6kohms. (3)Its C1 capacitance would be min 96pF and typ 120pF and max 144pF. (4)Its diode standoff voltage would be min 5.5V. (5)Its signal clamp voltage would be min 5.6V and typ 6.8V and max 8V for positive clamp and would be min -0.4V and typ -0.8V and max -1.2V for negative clamp. And so on. At present we have not got so much information about this IC and we would try hard to get more information about this IC and we would try hard to get more information about it. If you have any question or suggestion or want to know more information please contact us for details. Thank you!
